tive to the ground or .surfaceover which I the wheel is operated.

The invention embodies, among other fea tures, a device moreparticularly adapted for use in connection with automobile wheels andwhich includes a plurality of sections adapted for connection with thewheel to inclose the tire thereof, relatively interlocked and providedwith tread members, adapted to increase the traction between the wheeland the ground, particularly in instances .where the wheel is operatedover slippery ground or in sand.

In the further disclosure of the invention reference is to be had to theaccompanying drawings iconstituting a part of this specification, inwhich similar characters of reference denote corresponding parts in allthe views,and in which:

Figure 1 is a fragmentary side elevation a vehicle wheel, showing mydeyice mounted thereon; Fig. 2 is a fragmentary perspective view lookingat one end of one section, the same having been removed from the vehiclewheel; Fig. 3 is a fragmentary perspective view of the adjacent end ofthe next section, the same having been removed from the vehicle wheel;Fig. 4 is a vertical transverse 4-4 in Fig. 1: Fig. 5 is a verticaltransverse sectional view taken on the line 55 in Fig. 1 and Fig. 6 is aperspective view of one of the treads.

Referring more particularly to the views, 1 employ a casing 10, forconnection with the rim 11 of a vehicle wheel 12, such as an automobilewheel, the said wheel being provided with a pneumatic tire 13. .Thecasing 10 consists substantially of a plurality of sections 14, 15, withthe section 14 adapted for interlocking engagement with the section 15,as will be. hereinafter more fully disclosed. Adjacent each end of eachsection is mounted a securing member 16, comprising av plate 17 mountedto the sections being sectional view taken on the line' connectionbetween the i can be rea swmg on one side of t the section and havingthe free end thereof adapted for connection with a strap 18 mounted toswing on the other side of the section, the said plate 17 being adaptedto extend transversely to the rim of the vehicle wheel and provided withinwardly extending pins 19, rigidly secured to the plate 17 andextending laterally thereto, a bearing plate 20 being slidably mountedon the pins 19 as shown, an-expansible helical spring 21 being mountedto encircle each pin 19 of each plate 17, the said springs being-interposed between theplate 17 'and the bearing plate 20 to retain the plate20 in frictional engagement with the rim 11 when the-free end of theplate 17 is connected to the strap 18. The sections 14; 15 arepreferably U shaped in cross section, and when mounted to inclose thetire 13 are-adapted to be held rigidly 't0 the rim 11 of the vehiclewheel 12 by the securing members 16, inthe man ner mentioned above, itbeing readily seen that the expansibility of the springs 21 will holdthe. bearing plate 20 against the rim 11. and also cushionthe sections14,15 relatively to thev'ehicle wheel.

Bayonet'slots 22 are provided in the sides of the section 14 adjacenttheend thereof and are adapted to slidably receive there-, pins 23, securedthrough laterally extending to'the sides of the section'15, adjacent theend thereof, the said bayonet slots being formed so that when thesections 14, 15 are initially placed upon the vehicle wheel 12, the pins23 will extend into the forward portions 24 of the bayonet slots andwill then be moved to lie in the plane of the vertical port-ions 25 ofthe bayonet slots. Now when the securing members 16 are moved intosecuring position in the manner 'mentioned above, it will be readilyseen that the sections 14, 15 will be moved toward the rim 11 of thevehicle wheel, thus causing the pins 23 to move upwardly in thevertical. portions of the bayonet slots 22 and lie in the rear portionsof the bayonet slots so that if the tire 13 should deflate, the weightof the vehicle on the vehicle wheel Will not collapse or injure thesections 14, 15, it being readily seen that the section 14 the section15 in view of the pin and slot sections 14, 15, it being further seenthat by simply releasing the securin members '16, the sections 14, 15dily disengaged, the pins 23 of the section 15 being moved out of thebaywill ride or overlap vonet slots 22 of the section 14. It will befurther seen that by connecting the sections 14, in the mannermentioned, an end of one section will overlap an end of the nextadjacent section, thus forming a joint which will prevent small stonesand the like from entering the casing 10 and becoming wedged between thecasing and the tire 13.

A series of treads 27 are formed with or secured to the casing 10, thementioned treads being arranged in spaced relation on the sections 14, 15 and extending across the outer faces thereof, each tread 27 consistingsubstantially of an angle bar 28 having one portion thereof resting uponthe face of the casing and the other portion thereof extendingdiametrically outwardly .from:' the casing, the said angle barbeing-bent in a U-shaped torm'so that the ends thereof will overlap thesides of the casing,

-said overlapping ends being bolted or riveted to the casing to securethe tread 27 in rigid position on the casing.

' In the use of my device in connection with automobile wheels or othervehicle wheels, the sections 14, 15-can be readily connected to theWheel prior to advancing the vehitile over a slippery roadway or a sandyroadQ-it being-readily seen that with the use of the device described,the tractional effect of the vehicle Wheel will be greatly increased,thus preventing any slipping of the vehicle when yehicle, it beingreadily seen that it the the vehicle is advanced over a sandy or aslippery road, as" mentioned heretofore.

When the sections 14, 15 have been removed from the vehicle wheel, thementioned sections can be conveniently arranged in rel- "a-tivelyvadjacent position and conveniently secured'to the vehicle without in anymanner hampering the proper operation of the member-29 is mounted toswing on each sec- I tion 15 and movable to extend across a portion ofthe strap, thus retaining the same in engagement with the, plate 17 asshown in Fig. 3.

Having thus described my invention, I claim: y

A device of the class described comprising a. casing consisting of aplurality of connectible sections adapted to inclose the rim of avehicle wheel, a securing member mounted on each end of each section,said securing men1- bcr consisting of a plate mounted to swing on oneside of the section, a strap mounted to swing on the other side of thesection and adapted to be engaged by the free end of the said plate,pins extended laterally from the said plate, a bearing plate mounted toslide on the said pins and adapted to engage the rim of the vehiclewheel, and cxpansible helical springs mounted to encircle the said pinsand interposed between the said plate and the said bearing plate toretain the inner face of the said bearing plate in frictional contactwith the rim of the vehicle wheel.

In testimony whereof I aflix my signature in presence of two wltnesses.
